Question

(03.08 MC)

Two people recently traveled to another country and purchased a few sculptures made of ivory and brought them back to the United States. Elephant husk ivory is banned in many parts of the world. The sculptures were found by law enforcement officers and taken in as evidence. While analyzing the evidence, a forensic scientist extracted DNA from the ivory and performed a test on it that allowed the DNA to be compared to the DNA of an elephant. The scientist was able to conclude that the ivory was elephant husk ivory. What biotechnology was used to identify the source of the ivory?

DNA fingerprinting
cloning technology
polymerase chain reaction
transgenic technology
Question 2(Multiple Choice Worth 3 points)
(03.08 MC)

Which of the following best describes an advantage of artificial selection?

Can increase the variation in a certain species
Helps produce offspring having desired traits
Helps produce offspring who do not suffer from diseases
Can make species immune to changes in the environment
Question 3(Multiple Choice Worth 3 points)
(03.08 MC)

Which type of biotechnology is used by scientists when they alter the DNA of a plant to make it grow faster?

Genetic engineering, because the genes of the plants were modified
Genetic engineering, because it is always helpful to society
Artificial selection, because the DNA of the plant was changed
Artificial selection, because it always produces desirable traits
Question 4(Multiple Choice Worth 3 points)
(03.08 MC)

The following table describes some biotechnological processes.

Biotechnological Processes
Process Description
1 Producing offspring that have identical DNA as one parent
2 Crossing a high-yielding fruit variety with a high-vitamin variety

Which biotechnological processes are described in the table?
Both processes describe cloning.
Both processes describe genetic engineering.
Process 1 describes cloning, and process 2 describes artificial selection.
Process 1 describes artificial selection, and process 2 describes cloning.
Question 5(Multiple Choice Worth 3 points)
(03.08 MC)

A corn plant has been genetically engineered. It produces pollen that can make its own toxins. These toxins protect the corn plant against pests. What is a likely impact on the environment around the corn plant?

Bird and butterfly populations around the area may increase.
The concentration of pesticides in a nearby lake would increase.
Newer strains of pesticide-resistant pests may develop.
The carbon dioxide level would increase in the area.
Question 6(Multiple Choice Worth 3 points)
(03.08 MC)

Two methods of biotechnology used by scientists are described below.

Method X: Used genetic engineering to create a crop of corn that grows faster and is pest resistant
Method Y: Used artificial selection to create a new breed of dog that sheds less

Which method is likely to be more advantageous in agriculture?

Method X, because it increases the available food supply
Method X, because it protects the corn from diseases
Method Y, because it increases genetic diversity of dogs
Method Y, because it increases biodiversity of dogs
Question 7(Multiple Choice Worth 3 points)
(03.08 MC)

Which of the following is a disadvantage of artificial selection?

Does not allow selection of traits
Creates inferior versions of organisms
Reduces the variation in a certain species
Reduces yield of food from animals and crops
Question 8(Multiple Choice Worth 3 points)

Which technology has been commonly utilized by scientists to manipulate heritable information by separating DNA fragments into a unique pattern that can be compared to DNA fragments?

Gel electrophoresis
Gene cloning
Artificial selection
Restrictive enzyme analysis
